Specification of Letters Patent.

PatentedDec. 2,1913.

Application filed November 27, 1912. Serial No. 733,792.

To all whom it may concern Be it known that I, ALBERT WAKEFIELD, a citizen of the United States, residing at WVashington, in the District of Columbia, have invented certain new and useful Improvements in Conveyers, of which the following is a specification.

This invention relates to conveyors of that class characterized by parallel slats connected at their ends to links, the structure forming an endless belt.

It is the object of the present invention to provide in a conveyer of the kind stated a novel and improved link structure and means for securing the slats thereto, and to this end the invention consists in a combination and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing, in which Figure l is a plan view of a fragment of the conveyer embodying the structure which is the subject of the present invention. Fig. 2 is a longitudinal section on the line 22 of Fig. 1. Fig. 3 is a cross-section on the line 33 of Fig. 1.

Referring specifically to the drawing, 5 denotes the parallel cross-slats of the conveyer, said slats being connected at their ends to links 6, a pair of such linksbeing provided for each slatone for each end of the slat.

Each link comprises a flat body portion having an aperture 7 forthe teeth of the sprocket wheel over which the chains formed by the links pass. At one end of the body portion are two spaced hinge knuckles 8, and at the opposite end, at the center thereof, is a single hinge knuckle 9. The knuckle 9 is adapted to fit between the knuckles 8 of the next link, and a hinge connection therebetweenis had by a pin 10 passing through the matching knuckles.

Between the knuckles 8 is located a hook comprising an upstanding shank 11 extending at a right angle to the body of the link from the edge thereof which is between the knuckles, and a bill 12 which is a downturned portion at the outer end of the shank.

The slats 5 are reduced in width at their ends, as indicated at 13, to form tenons which extend into the sockets formed by the herein-described hooks of the links. The tenons fit snugly in the hooks, and the shoulders formed by the tenons abut against the inner edges of the hooks, whereby the slats are held against longitudinal displacement. The ends of the slats are also cut away at the bottom to the extent of the thickness of the body of the links to bring that portion of the bottom of the slats extending between the links flush with the bottom or under side thereof. This structure enables the slats to ,travel close to the floor of a chute or other structure over which the conveyer is designed to operate.

A llnk constructed as herein described can be easily and cheaply manufactured, the manner of securing the slats enables the conveyer to be readily assembled, and the slats are securely held in place.

I claim:

A conveyer comprising a plurality of slats reduced in width at their ends to form tenons, and links across the top of which the end portions of the slats extend, each of said links comprising a flat body portion having hinge knuckles at its ends and an opening intermediate said ends, between which opening and one end of the body portion the latter has a hook comprising an upstanding shank and a downturned bill, said parts forming a socket to receive the tenon on one end of a slat, the shoulder formed by said tenon abutting against one edge of the shank and bill, and the bottom of the slats at the ends thereof being cut away to the extent of the thickness of the body portion to bring the under side of the slat flush with the under side of the body portion, and said cut-away portion of the slat making a shoulder which abuts against the inner edge of the link.

In testimony whereof I aflix my signature in presence of two witr i esses.
